A practical nurse is assigned to care for a client who is two hours postoperative following a subtotal thyroidectomy. To minimize swelling and protect the surgical airway, which position is most appropriate for the nurse to place the client in?

Semi-Fowler's position with pillows supporting the head and neck

Supine position with a small rolled towel placed directly under the shoulders

High-Fowler's position with the neck flexed so the chin rests near the chest

Left lateral recumbent position with the head resting flat on the mattress

Show answer & explanation

Answer: Semi-Fowler's position with pillows supporting the head and neck

Answer

Semi-Fowler's position with pillows supporting the head and neck

The correct action is to place the client in a Semi-Fowler's position while providing support to the head and neck. Elevating the head of the bed 30 to 45 degrees utilizes gravity to reduce postoperative swelling and venous pressure in the neck region. Supporting the head and neck with pillows ensures they remain in a neutral alignment, which prevents both flexion and hyperextension. This neutral positioning protects the surgical incision from tension, reduces pain, and ensures the airway remains fully open.

Step-by-Step Solution

Identify the surgical procedure and its specific postoperative risks.

The client underwent a thyroidectomy, which carries high risks of neck edema, airway obstruction, and incision strain.

Understanding the anatomical risks dictates the appropriate basic care and positioning required for safety.

Determine the ideal bed angle to manage these specific risks.

The head of the bed should be elevated 30 to 45 degrees, known as Semi-Fowler's position.

Elevation uses gravity to reduce venous pressure, minimizing fluid accumulation and swelling in the delicate neck area.

Select the appropriate support method for the affected body part.

The head and neck must be supported in a neutral position using pillows or sandbags.

Maintaining neutral alignment prevents both hyperextension and hyperflexion, avoiding any tension on the fragile suture line.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first ensure the client rests supine to reduce swelling, then turn the stocking inside out to the heel, place it over the foot and heel, slide it up the calf, and finally smooth out any wrinkles.

To properly apply anti-embolism stockings, the practical nurse must first reduce venous swelling by having the client rest supine. Next, preparing the stocking by turning it inside out to the heel makes it easier to slip over the foot. After anchoring it on the foot and heel, the stocking is pulled up the leg. Finally, the nurse must ensure there are no wrinkles or rolled areas, which could act like a tourniquet and constrict blood flow.

Step-by-Step Solution

Prepare the client's legs

The client rests supine for at least 15 minutes.

To reduce venous stasis and swelling in the lower extremities before application.

Prepare the stocking

The stocking is turned inside out down to the heel.

To facilitate smooth application over the foot and prevent bunching.

Apply to the foot

The stocking covers the toes, foot, and heel.

To properly anchor the stocking on the foot before pulling it up.

Apply to the leg

The stocking is pulled up the calf.

To provide the intended graduated compression to the lower leg.

Perform a final check

Wrinkles and rolled edges are smoothed out.

To prevent constriction of blood flow which can cause tissue damage.

Question 703Question →

An adult client is undergoing post-procedure care on a medical-surgical unit following a percutaneous liver biopsy. The client is currently positioned on the right side with a rolled towel under the puncture site. During the 4-hour post-procedure assessment, the licensed practical nurse notes that the client's heart rate has climbed to 108 beats per minute from a pre-procedure baseline of 76 beats per minute. The blood pressure is currently 104/62 mm Hg, compared to a baseline of 128/74 mm Hg. The client reports new-onset, moderate pain in the right shoulder. Based on these assessment findings, which action must the nurse take to reduce the risk of a severe complication?

Maintain the client in the current position and immediately report the findings to the supervising registered nurse.

Assist the client into a semi-Fowler's position to alleviate the shoulder discomfort and administer a prescribed analgesic.

Document the referred shoulder pain as an expected procedural outcome and recheck the vital signs in one hour.

Delay further movement, apply supplemental oxygen, and independently initiate a STAT complete blood count draw.

Show answer & explanation

Answer: Maintain the client in the current position and immediately report the findings to the supervising registered nurse.

Answer

The nurse must maintain the client in the right side-lying position to apply continuous pressure to the biopsy site and immediately notify the supervising registered nurse of the findings.

Following a percutaneous liver biopsy, maintaining the client in a right side-lying position is essential to provide direct pressure (tamponade) to the biopsy site, preventing hemorrhage from the highly vascular liver tissue. The client's rising heart rate, dropping blood pressure, and new-onset right shoulder pain (referred pain from diaphragmatic irritation due to internal bleeding) are classic signs of early hypovolemic shock. The priority is to keep the physical pressure on the puncture site and immediately escalate these critical findings to the supervising registered nurse for rapid medical intervention.

Step-by-Step Solution

Analyze the client's post-operative vital signs.

The heart rate has increased significantly (76 to 108) and blood pressure has decreased (128/74 to 104/62).

These downward trends in blood pressure paired with tachycardia are classic early indicators of hypovolemic shock, likely due to internal hemorrhage.

Evaluate the clinical significance of the right shoulder pain.

The pain is recognized as referred pain caused by blood accumulating under the diaphragm and irritating the phrenic nerve.

Combined with the vital sign changes, this confirms a high suspicion of active internal bleeding from the highly vascular liver.

Determine the priority nursing intervention within the practical nurse scope of practice.

The nurse must keep the client on the right side to maintain pressure on the liver capsule and immediately notify the RN.

Repositioning would remove the tamponade effect, and delaying escalation to draw labs or document would lead to cardiovascular collapse.

Question 704Question →

A client who underwent a right-sided supratentorial craniotomy two days ago is currently receiving continuous enteral feedings via a nasogastric tube. The practical nurse is preparing to provide a complete bed bath and change the soiled bottom sheets. What is the safest method for the nurse to execute these care tasks?

Lower the bed to a completely flat position to ensure the spine remains perfectly straight while the team log-rolls the client.

Apply soft wrist restraints temporarily before starting the hygiene routine to prevent accidental dislodgment of the feeding tube.

Maintain the bed at a 30-degree incline while turning the client laterally, ensuring the head and neck remain in a neutral midline alignment.

Position the client upright at a 90-degree angle and gently guide the chin toward the chest to gain adequate access to the posterior neck.

Show answer & explanation

Answer: Maintain the bed at a 30-degree incline while turning the client laterally, ensuring the head and neck remain in a neutral midline alignment.

Answer

The practical nurse should maintain the head of the bed at a 30-degree elevation and keep the client's head and neck in a neutral, midline position while turning them.

Following a supratentorial craniotomy, it is critical to promote venous drainage from the brain to prevent life-threatening increases in intracranial pressure. This is achieved by keeping the head of the bed elevated at 30 to 45 degrees and ensuring the neck is not flexed or rotated. Additionally, because the client is receiving continuous enteral feedings, maintaining this elevation is mandatory to prevent regurgitation and pulmonary aspiration. Turning the client laterally while preserving this 30-degree incline and neutral neck alignment perfectly balances the client's hygiene needs with their strict neurological and respiratory safety requirements.

Step-by-Step Solution

Analyze the client's surgical history.

The client had a supratentorial craniotomy two days ago.

This surgery requires specific positioning to promote cerebral venous drainage and prevent increased intracranial pressure (ICP), specifically elevating the head of the bed 30 to 45 degrees and maintaining neutral head alignment.

Identify the risks associated with the ongoing therapy.

The client is receiving continuous enteral feedings and is at high risk for aspiration.

Keeping the head of the bed elevated at least 30 degrees is mandatory to prevent regurgitation and pulmonary aspiration of the feeding formula.

Evaluate the proposed basic care techniques against these constraints.

Turning the client must be accomplished without lowering the bed flat and without flexing or hyperextending the neck.

Flat positioning or neck flexion would dangerously spike ICP and simultaneously increase aspiration risk.

Key Concept

Positioning principles for clients with increased intracranial pressure risk and continuous enteral feedings.

Question 705Question →

An older adult client is receiving care on a medical unit for a suspected upper gastrointestinal bleed. The morning laboratory report indicates a hemoglobin level of $6.9 \text{ g/dL}$ and a serum potassium of $2.8 \text{ mEq/L}$ . The client's current vital signs are: blood pressure $96/60 \text{ mm Hg}$ , apical pulse $116 \text{ beats/minute}$ , and respirations $22 \text{/minute}$ . A registered nurse (RN) prepares a prescribed intravenous (IV) piggyback of potassium chloride, hands the bag to the practical nurse (PN), and delegates the medication administration and subsequent monitoring of this client. Which action is most appropriate for the PN to take?

Decline the delegation, as caring for a hemodynamically unstable client with critical laboratory abnormalities requires continuous registered nurse (RN) assessment.

Accept the assignment but initiate vital sign checks every 15 minutes, attributing the client's tachycardia and mild hypotension to the expected effects of dehydration.

Administer the IV potassium chloride to resolve the hypokalemia, and document the low hemoglobin in the electronic health record for the provider to review during afternoon rounds.

Proceed with hanging the IV medication at the prescribed rate, relying on the RN's verbal confirmation of the correct medication and client identity to save time.

Show answer & explanation

Answer: Decline the delegation, as caring for a hemodynamically unstable client with critical laboratory abnormalities requires continuous registered nurse (RN) assessment.

Answer

The practical nurse must decline the delegation because the client is exhibiting signs of hemodynamic instability and hypovolemic shock, which requires the advanced assessment skills of a registered nurse.

The client is demonstrating clear signs of active bleeding and hypovolemic shock (hemoglobin

6.9 \text{ g/dL}

, hypotension, tachycardia) alongside severe hypokalemia. Caring for a hemodynamically unstable client requires advanced physiological assessment, clinical judgment, and immediate intervention that falls exclusively within the scope of practice of a registered nurse (RN). The practical nurse (PN) must advocate for client safety by declining this inappropriate delegation.

Step-by-Step Solution

Analyze the laboratory data provided in the scenario.

The client has a hemoglobin of

6.9 \text{ g/dL}

(critically low, indicating severe blood loss) and a potassium of

2.8 \text{ mEq/L}

(critically low, risking cardiac dysrhythmias).

Identifying abnormal laboratory values is essential for recognizing physiological risk.

Analyze the vital signs in the context of the client's diagnosis.

A blood pressure of

96/60 \text{ mm Hg}

and a heart rate of

116 \text{ beats/minute}

in a client with a suspected gastrointestinal bleed indicate compensatory tachycardia and hypotension.

These are classic early signs of hypovolemic shock, meaning the client's condition is actively deteriorating.

Evaluate the appropriateness of the RN's delegation.

The RN is delegating the care, medication administration, and monitoring of a highly unstable client to the PN.

The PN scope of practice involves caring for clients with predictable outcomes. Unstable clients require advanced assessment and clinical judgment.

Determine the correct nursing action based on scope of practice.

The PN must decline the unsafe assignment to protect the client and practice safely within legal boundaries.

Accepting an unstable client assignment violates the PN scope of practice and places the client at severe risk for adverse outcomes.

Key Concept

Reduction of Risk Potential through appropriate delegation and recognition of hemodynamic instability.

Question 706Question →

The electronic barcode scanner on a unit's medication cart is unexpectedly malfunctioning due to a network outage. A practical nurse is preparing to administer a scheduled dose of oral amlodipine to an alert client who is resting in bed. Which action must the nurse take to ensure safe medication administration?

Proceed with administration based on visual recognition, as the nurse has consistently cared for this client over the past two days.

Ask the client to state their full name and date of birth, comparing this information against the wristband and the medication administration record.

Verify the client's identity by cross-referencing the medication administration record with the room and bed number posted on the wall.

Delegate the identification verification to the unlicensed assistive personnel who recently obtained the client's vital signs.

Show answer & explanation

Answer: Ask the client to state their full name and date of birth, comparing this information against the wristband and the medication administration record.

Answer

The nurse must manually ask the client to state their full name and date of birth, and compare this against the client's wristband and the medication administration record.

Safe medication administration requires the nurse to verify two distinct client identifiers, typically the client's full name and date of birth. When an electronic barcode scanner is malfunctioning, the nurse must manually ask the alert client to state these identifiers and compare them directly against the identification wristband and the medication administration record (MAR) to guarantee the medication is given to the correct individual.

Step-by-Step Solution

Identify the standard of practice for client identification when electronic barcode systems fail.

The standard requires manual verification of two distinct, approved client identifiers.

Ensuring the "right client" is a fundamental rule of safe pharmacological therapy that cannot be bypassed during equipment outages.

Evaluate the proposed identification methods in the options against safety protocols.

Using the client's stated name and date of birth compared to the wristband and MAR is the only approved manual method.

Room numbers, visual recognition, and delegating to assistive personnel are unsafe practices that violate medication administration protocols.

Question 707Question →

A practical nurse (PN) is reviewing the electronic health record and collecting data on a client who is $12$ hours postoperative following an exploratory laparotomy. The client's preoperative baseline data showed a hemoglobin of $13.8\text{ g/dL}$ , a blood pressure of $132/78\text{ mm Hg}$ , and a heart rate of $76\text{ beats/min}$ . The current morning laboratory results show a hemoglobin of $9.6\text{ g/dL}$ . Upon assessment, the client's blood pressure is $102/64\text{ mm Hg}$ , heart rate is $114\text{ beats/min}$ , and the client reports feeling restless and lightheaded when the head of the bed is elevated. Which action should the PN take first?

Lower the head of the bed to a supine position and immediately notify the registered nurse (RN).

Document the findings as expected postoperative hemodilution and continue routine vital sign monitoring.

Independently increase the rate of the continuous intravenous fluid infusion to treat the lightheadedness.

Administer a prescribed PRN oral analgesic, assuming the elevated heart rate is a physiological response to postoperative pain.

Show answer & explanation

Answer: Lower the head of the bed to a supine position and immediately notify the registered nurse (RN).

Answer

Lower the head of the bed to a supine position and immediately notify the registered nurse (RN).

The client is exhibiting early signs of hypovolemic shock due to acute blood loss, evidenced by a significant drop in hemoglobin (greater than

2\text{ g/dL}

), tachycardia, borderline hypotension, restlessness, and orthostatic symptoms. The PN must prioritize client safety by placing them supine to promote venous return to the brain and vital organs, and immediately escalate the critical findings to the RN for further assessment and intervention.

Step-by-Step Solution

Compare the client's current laboratory values and vital signs to their preoperative baseline.

Hemoglobin dropped by

4.2\text{ g/dL}

, heart rate increased by

38\text{ beats/min}

, and blood pressure decreased significantly.

Identifying trends is crucial for recognizing postoperative complications like internal bleeding.

Correlate the objective data with the client's subjective symptoms (restlessness, lightheadedness when elevated).

The combination of findings strongly suggests reduced oxygen-carrying capacity and impending hypovolemic shock.

Restlessness is an early sign of hypoxia, and orthostatic lightheadedness indicates poor cerebral perfusion.

Determine the safest, most immediate action within the practical nurse scope of practice.

Position the client flat (supine) to optimize blood flow to the brain and notify the RN immediately.

The PN must mitigate immediate physical risk while escalating to the RN who can perform advanced assessments and obtain medical orders for fluid or blood resuscitation.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for collecting a clean-catch midstream urine specimen ensures the sample is not contaminated by external skin flora. The nurse must first apply gloves, cleanse the area appropriately, allow the client to initiate the stream to flush the urethra, catch the midstream urine in the sterile cup, and finally secure the container.

The established standard of care for a clean-catch urine culture requires a specific sequential approach: preparation (hand hygiene/gloves), decontamination (cleaning front to back), urethral flushing (voiding a small amount), collection (midstream catch), and securement. This evidence-based order strictly reduces the risk of altering laboratory findings with environmental flora.

Step-by-Step Solution

Perform hand hygiene and don clean gloves.

Readiness to handle the client and equipment safely.

Standard precautions reduce the risk of cross-contamination before beginning any clinical procedure.

Question 710Question →

A client is admitted to the surgical unit directly from the recovery room after undergoing a subtotal thyroidectomy. To promote optimal comfort and prevent postoperative complications, which positioning strategy should the practical nurse implement?

Place the client in a semi-Fowler's position and arrange supportive pillows on both sides of the neck.

Keep the mattress completely flat and assist the client into a lateral decubitus position.

Position the client supine with a small rolled towel situated beneath the shoulder blades.

Adjust the bed into a high-Fowler's position and encourage the client to rest their chin on their chest.

Show answer & explanation

Answer: Place the client in a semi-Fowler's position and arrange supportive pillows on both sides of the neck.

Answer

Place the client in a semi-Fowler's position and arrange supportive pillows on both sides of the neck.

Following a thyroidectomy, it is critical to prevent swelling around the trachea and to avoid stressing the incision line. Placing the client in a semi-Fowler's position uses gravity to minimize venous pooling and edema in the neck. Surrounding the head and neck with supportive pillows maintains neutral alignment, preventing both hyperflexion and hyperextension, thereby protecting the airway and the integrity of the sutures.

Step-by-Step Solution

Identify the anatomical location of the surgical procedure and its associated risks.

The client had a subtotal thyroidectomy, which carries high risks for airway obstruction due to neck edema and incision rupture from tension.

Understanding the surgical site dictates the required basic care and positioning.

Evaluate how gravity and body alignment affect the surgical site.

An upright or semi-upright position uses gravity to reduce swelling, while neutral neck alignment prevents pulling on the sutures.

Edema near the trachea can quickly cut off the airway, making swelling reduction the top physiological priority.

Select the positioning intervention that best achieves both comfort and safety.

Semi-Fowler's position with lateral head support achieves both reduced edema and neutral neck alignment.

This directly satisfies the requirement for optimal postoperative positioning following neck surgery.

Key Concept

Postoperative care for thyroidectomy requires minimizing neck edema and preventing tension on the surgical incision through specific upright, neutral body alignment.

Show answer & explanation

Answer: Withhold the metoprolol, assist the client into a supine position, and promptly notify the registered nurse of the assessment findings.

Answer

Withhold the metoprolol, assist the client into a supine position, and promptly notify the registered nurse of the assessment findings.

The client is exhibiting early signs of decreased cardiac output and poor tissue perfusion, evidenced by hypotension, dizziness, and pallor. The elevated heart rate is a vital compensatory mechanism working to maintain cardiac output. Administering metoprolol, a beta-blocker, would dangerously lower both the heart rate and the blood pressure. The practical nurse's priority is to ensure immediate safety by holding the medication, placing the client flat to improve cerebral perfusion, and promptly escalating the situation to the registered nurse.

Step-by-Step Solution

Analyze the vital signs and the client's physical presentation.

The client has a low blood pressure (

92/58 \text{ mmHg}

), a rapid heart rate (

114 \text{ beats per minute}

), and symptoms indicating poor cerebral perfusion (pallor, dizziness).

Recognizing early signs of shock or hemodynamic instability is critical for ensuring client safety.

Evaluate the planned medication against the clinical findings.

Metoprolol is a beta-blocker that lowers both heart rate and blood pressure, making it strictly contraindicated in this hemodynamically unstable state.

Administering the medication would dangerously blunt the compensatory tachycardia and worsen the hypotension.

Determine the priority nursing action within the practical nurse's scope of practice.

The medication must be withheld, the client placed in a safe supine position to optimize blood flow to the brain, and the registered nurse notified immediately.

Hemodynamic instability requires rapid assessment by a registered nurse and potential provider intervention.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: perform hand hygiene and don gloves, cleanse the site and let it air dry, puncture the finger, wipe away the first drop of blood, and finally apply the second drop of blood to the test strip.

Following the correct chronological sequence ensures that standard precautions are maintained, the site is properly prepped without alcohol interference, and the specimen is undiluted by tissue fluid. This methodical approach directly reduces the risk of inaccurate laboratory results and subsequent incorrect insulin administration.

Step-by-Step Solution

Perform hand hygiene and put on clean gloves.

Standard precautions are established.

Reduces the risk of pathogen transmission between the nurse and the client.

Cleanse the lateral aspect of the finger with an alcohol swab and allow it to air dry.

The puncture site is prepared and free of wet alcohol.

Wet alcohol can mix with the blood sample, causing inaccurate readings and increased pain for the client.

Puncture the side of the fingertip using a sterile lancet.

Capillary blood flow is initiated.

The lateral aspect of the finger provides adequate blood flow with less discomfort than the center of the finger pad.

Wipe away the first drop of blood using a clean gauze pad.

Interstitial fluid is removed from the puncture site.

The initial drop contains tissue fluid that can dilute the blood and result in a falsely low glucose reading.

Apply the next drop of blood to the reagent test strip.

An accurate glucose measurement is obtained.

The second drop consists of pure capillary blood, reducing the risk of clinical errors based on false lab values.

Key Concept

Proper procedural technique for capillary blood glucose testing to ensure accurate diagnostic values.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with cleaning the eye to prevent contamination, positioning the client's head to reduce the blink reflex, retracting the lower eyelid to expose the conjunctival sac, instilling the drop safely into the sac, and finally applying pressure to the nasolacrimal duct to prevent systemic absorption.

The correct sequence ensures the eye is clean, properly positioned to receive the medication without inducing a blink reflex, opened to expose the conjunctival sac where the drop is placed to avoid corneal injury, and finally occluded to prevent systemic absorption of the drug.

Step-by-Step Solution

Cleanse the eyelid and eyelashes from inner to outer canthus.

The eye area is free of debris and drainage.

Maintaining a clean field prevents the introduction of bacteria into the eye during administration.

Instruct the client to tilt the head back and look up.

The eye is optimally positioned.

Looking upward redirects the cornea away from the dropper, which reduces the natural blink reflex.

Retract the lower eyelid downward.

The lower conjunctival sac is exposed.

Creating a pocket ensures the medication is delivered safely without falling directly onto the sensitive cornea.

Instill the drop into the conjunctival sac.

Medication is delivered to the proper anatomical site.

The conjunctival sac distributes the medication evenly across the eye without causing trauma.

Apply pressure to the nasolacrimal duct.

The tear duct is temporarily blocked.

Occluding the duct prevents the beta-blocker from entering systemic circulation, which could inappropriately lower the client's heart rate.

A client is transferred to the clinical unit following a percutaneous needle biopsy of the liver. The practical nurse (PN) is preparing to settle the client in bed. To minimize the risk of hemorrhage from the puncture site, what position should the PN help the client maintain?

Right lateral position with a folded towel placed under the rib cage

Left lateral position with the head of the bed elevated 30 degrees

Supine position with the knees flexed and supported by a pillow

High Fowler's position with the arms resting on an overbed table

Show answer & explanation

Answer: Right lateral position with a folded towel placed under the rib cage

Answer

The client should be assisted into the right lateral position with a folded towel or small pillow under the right rib cage.

Because the liver is a highly vascular organ located on the right side of the body, a percutaneous biopsy carries a significant risk of internal bleeding. Placing the client in a right lateral (side-lying) position, often with a towel roll beneath the puncture site, uses the client's body weight to apply direct pressure to the liver capsule. This pressure is essential for promoting hemostasis and preventing hemorrhage.

Step-by-Step Solution

Identify the anatomical location of the liver.

The liver is located in the right upper quadrant of the abdominal cavity.

Knowing the organ's location dictates where localized pressure must be applied.

Determine the priority post-procedure risk for a percutaneous liver biopsy.

The primary risk following a biopsy of this highly vascular organ is hemorrhage.

Preventing blood loss is the most critical immediate post-procedure intervention.

Select the client position that safely applies external pressure to the puncture site.

The right side-lying (lateral) position uses the client's body weight to compress the liver.

Direct mechanical pressure promotes hemostasis and minimizes bleeding.

Show answer & explanation

Answer: Withhold the scheduled dose of enoxaparin and immediately notify the registered nurse.

Answer

Withhold the scheduled dose of enoxaparin and immediately notify the registered nurse.

The client's clinical picture—a significant drop in hemoglobin combined with new-onset tachycardia, a decrease in baseline blood pressure, and lightheadedness—strongly suggests acute postoperative bleeding or early hemorrhagic shock. The practical nurse must prioritize safety by withholding the anticoagulant medication, which could exacerbate bleeding, and immediately escalating these critical findings to the registered nurse for provider notification and potential medical intervention.

Step-by-Step Solution

Analyze the client's vital signs and laboratory trends in the provided table.

Identified a significant drop in hemoglobin (2.2 g/dL decrease), accompanied by new-onset tachycardia (114 beats/min) and hypotension (100/62 mm Hg).

Comparing current data to baseline is essential for recognizing subtle or acute physiological changes.

Correlate the objective data with the client's subjective report of feeling lightheaded.

Recognized that these combined findings strongly indicate early hemorrhagic shock or active postoperative bleeding.

Connecting symptoms with vital sign trends determines the clinical severity of the situation.

Evaluate the safety of the scheduled medications based on the client's current status.

Determined that administering enoxaparin (an anticoagulant) is contraindicated in the presence of suspected active bleeding.

Administering high-risk medications without synthesizing the current clinical picture can lead to adverse client outcomes.

Question 716Question →

Following a lumbar puncture, an adult client is admitted to the medical-surgical unit for observation. The client is awake, alert, and has stable vital signs. Which positioning measure must the practical nurse implement to minimize the risk of complications?

Maintain the client in a flat, supine position for the duration prescribed by the healthcare provider.

Assist the client into a side-lying position with the knees drawn up tightly toward the chest.

Elevate the head of the bed to a 45-degree angle to promote optimal respiratory expansion.

Place the client in a prone position with a small pillow tucked under the abdomen for spinal support.

Show answer & explanation

Answer: Maintain the client in a flat, supine position for the duration prescribed by the healthcare provider.

Answer

Maintain the client in a flat, supine position for the duration prescribed by the healthcare provider.

Following a lumbar puncture, the client should be kept in a flat, supine position for several hours as prescribed by the provider. This position is critical because it helps prevent a post-dural puncture headache (often called a spinal headache) by reducing the gravitational hydrostatic pressure that causes cerebrospinal fluid (CSF) to leak from the dural puncture site.

Step-by-Step Solution

Analyze the physiological impact of the procedure.

A lumbar puncture involves puncturing the dura mater to access the subarachnoid space, which creates a small pathway where cerebrospinal fluid (CSF) can potentially leak.

Understanding the procedure highlights the specific post-procedure risks, primarily a post-dural puncture headache (spinal headache).

Evaluate the effect of gravity and positioning on CSF pressure.

Sitting upright or elevating the head increases hydrostatic pressure on the lower spine, forcing more CSF out of the puncture site.

Identifying what exacerbates the complication dictates the required nursing intervention.

Determine the optimal therapeutic position.

A flat, supine position distributes pressure evenly and minimizes gravitational force on the lumbar puncture site, allowing the dura to seal.

This directly mitigates the primary complication associated with the procedure.

A practical nurse is preparing to administer a scheduled transdermal medication patch to a client. Arrange the following steps for administration in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first perform hand hygiene and don gloves, then remove the old patch and clean the area, followed by selecting a new site, applying the new patch, and finally documenting the administration.

Transdermal patch administration must follow a logical safety sequence. First, the nurse protects themselves by performing hand hygiene and donning gloves. Second, the nurse removes the old patch and cleanses the skin to prevent an accidental overdose. Third, the nurse selects a new site to prevent skin irritation. Fourth, the new patch is applied and secured. Finally, the nurse documents the procedure to ensure clear communication with the healthcare team.

Step-by-Step Solution

Perform hand hygiene and put on clean gloves.

The nurse's hands are clean and protected.

This is always the first step to maintain infection control and prevent the nurse from accidentally absorbing the transdermal medication.

Remove the previously applied patch and cleanse the skin area.

The old patch and residual medication are removed.

Leaving an old patch on while applying a new one can lead to a dangerous medication overdose.

Select a new, clean, and hairless site for application.

A suitable site for the new patch is identified.

Site rotation prevents skin irritation and breakdown, while a hairless area ensures good adhesion.

Apply the new patch and press firmly to ensure adherence.

The new patch is securely attached to the client's skin.

Firm pressure ensures the patch will not fall off and the medication will be absorbed properly.

Document the administration, including the site, date, and time.

The medication administration record is updated.

Documentation must occur immediately after administration to maintain accurate health records and communicate with the care team.

Key Concept

The safe and systematic administration of transdermal medications requires preventing self-exposure, avoiding overdose by removing the old patch first, and ensuring proper site rotation.

Question 718Question →

An adult client is prescribed a 24-hour urine collection to evaluate kidney function and creatinine clearance. In which order should the nurse implement the steps of this procedure? Arrange the actions from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with having the client void and discarding that urine, noting the exact time as the start, collecting all subsequent urine in a cooled container, and ending with one final void added exactly 24 hours later.

A 24-hour urine collection requires precise timing and strict collection protocols to yield accurate diagnostic results. The procedure mandates starting with an empty bladder (discarding the first void) to ensure only urine produced during the 24-hour timeframe is measured. The exact time of this first void marks the official start. From then on, every drop of urine must be collected and kept cool to preserve its chemical integrity. Finally, exactly 24 hours after the start time, the client must void one last time to complete the physiological sample window.

Step-by-Step Solution

Empty the bladder and discard the initial void.

The bladder is completely empty, ensuring no urine produced prior to the 24-hour window is included.

Including prior urine falsely elevates the total 24-hour solute excretion measurement.

Record the start time.

A definitive timeline is established for the 24-hour window.

Diagnostic accuracy requires exactly 24 hours of physiological output; the start time dictates the end time.

Collect all subsequent urine and keep it cool.

All urine produced during the window is preserved.

Refrigeration or ice prevents degradation of the specimen and bacterial proliferation which could alter lab values.

Obtain a final void exactly 24 hours later.

The final urine produced within the testing window is captured.

This ensures the entire 24-hour physiological output is accounted for in the diagnostic test.

Question 719Question →

A practical nurse is conducting a postoperative assessment on a $72$ -year-old client who underwent a transurethral resection of the prostate (TURP) three hours ago. The client is receiving continuous bladder irrigation (CBI). Which clinical finding requires the most immediate escalation to the supervising registered nurse?

A gradual increase in the client's resting heart rate from

76

114

beats per minute over the past hour.

A postoperative serum sodium level reported as

138

mEq/L (

138

mmol/L).

The bedside barcode scanner malfunctions while the nurse is preparing to administer a scheduled oral multivitamin.

An unlicensed assistive personnel (UAP) is observed emptying the urinary drainage bag and recording the output volume.

Show answer & explanation

Answer: A gradual increase in the client's resting heart rate from $76$ to $114$ beats per minute over the past hour.

Answer

The correct answer is the gradual increase in the resting heart rate from

76

114

beats per minute, which is an early indicator of hypovolemic shock or severe hemorrhage.

A steadily increasing heart rate in a postoperative client is a classic early, compensatory sign of hypovolemia and potential hemorrhage. Because the client recently underwent a highly vascular prostate resection, this subtle cardiovascular change requires immediate escalation to the registered nurse for prompt intervention and evaluation of bleeding.

Step-by-Step Solution

Analyze the client's postoperative timeframe and current therapy.

The client is three hours post-TURP receiving continuous bladder irrigation, making them at high risk for hemorrhage and fluid shifts.

Identifying the procedure context helps anticipate potential life-threatening complications.

Evaluate the vital sign trend.

A heart rate increase from

76

114

beats per minute is a significant physiological change.

Tachycardia is often the first subtle, compensatory sign of hypovolemia and hemorrhage before the blood pressure drops.

Review the remaining clinical findings for priority.

The serum sodium is normal, the medication technical issue is low acuity, and the UAP's action is within their scope of practice.

Using the ABC (Airway, Breathing, Circulation) framework confirms that the cardiovascular change is the highest priority requiring immediate escalation.

Question 720Question →

A practical nurse is caring for a toddler who weighs $14$ kg and is diagnosed with acute otitis media. The healthcare provider prescribes cefdinir $7$ mg/kg PO every $12$ hours. The pharmacy dispenses cefdinir oral suspension labeled $125$ mg / $5$ mL. How many mL should the nurse administer for one dose? (Record answer to the nearest tenth. Do not include units in answer.)

Show answer & explanation

Answer: 3.9

Answer

3.9

To determine the correct administration volume, first calculate the total desired dose for the child:

14

\times 7

mg/kg =

98

mg. Next, calculate the volume using the medication concentration provided by the pharmacy. Divide the desired dose (

98

mg) by the available dose (

125

mg), and multiply by the available volume (

5

mL):

(98 / 125) \times 5 = 3.92

mL. Rounding this value to the nearest tenth provides the final answer of

3.9

Step-by-Step Solution

Calculate the total milligrams required for a single dose.

14 \text{ kg} \times 7 \text{ mg/kg} = 98 \text{ mg}

The prescription is weight-based, requiring the child's weight in kilograms to be multiplied by the ordered amount per kilogram.

Determine the volume of suspension needed to provide the desired dose.

\frac{98 \text{ mg}}{125 \text{ mg}} \times 5 \text{ mL} = 3.92 \text{ mL}

Applying the dimensional analysis or desired-over-have formula to calculate the liquid volume to administer.

Round the final answer to the nearest tenth.

3.9

The question explicitly requires rounding to the nearest tenth for administration.
